3.2 Data and Tools Requirements 3.2.1 Data Needs The data in this research came from several sources. Some information were collected by conducting an interview, questionnaire and discussion with expert from Plantation Office, BAPPEDA Musi Banyuasin Regency and Assessment Institute for Agricultural Technology BPTP South Sumatra Province. They have a good knowledge and experience in the study area. Things discussed with experts were concept and procedure of land suitability evaluation, and implementation of spatial multi criteria evaluation in land evaluation. Spatial data and literature were gathered from several institutions, based on field survey of previous research. The data consist of vector or raster format and non spatial data. Description of type and sources of spatial data is given in Table 2.

3.3 Method

The Method of this research was based on multi criteria decision making by implementing GIS model technology using spatial multi criteria evaluation that will determine location of oil palm plantation potential. Each criterion and alternatives should be evaluated and weighted using pairwise comparison method to determine the best location for oil palm plantation potential in Musi Banyuasin Regency. The research framework is show in Figure 4.
